This invention has reference to machines for the treatment of yarn and other fabrics, leather. and the like with liquids for dyeing, sizing, bleaching and similar treatments and it is intended to faciliate and accelerate the process of manufacture and to improve the qualities of the goods obtained by the treatment. The invention is particularly adapted for the treatment of broad oods with dyeing, bleaching and similar fiiquors and, in view thereof, it devises means of turning out a greater quantity of a superior rade of treated material than it was possib e, as far as I am aware, in accordance with the previous art, The dyeing of piece goods of textile fabrics, for instance, is associated with a variety of working procedures, such as thepreliminary cooking or bucking Mor the removal of the size of the goods to be dyed; then the subsequent rinsing after the dyeing, the oxidation by the action of the 8.11" and the subsequent treatment of the glpod? kwith the boiling soap liquors and t e i 0.

been carried out by means of the well known .dyeing-jigger with stationary trough and guiding rollers disposed therein; or two such jiggers were serially disposed of which one was used for the dyeing and the other served for rinsing or similar purposes. It was not possible, however, in accordance with the previous art, to carry out the working procedures above enumerated on one and the same machine, but it was necessary to cause the goods to pass from one machine to the other; or, 1n the case of only one jig er being used, it was necessary to empty t 0 same after each articular working procedure and to mal e it ready for the succeeding one whereby progress of the chemistry of dyeing and coloring agents, however, it became im erative to devise means for allowing t ese and other various working procedures to be carried out in direct succession and uninterruptedly and without any substantial stoppage of the passage of the goods.

ow, in accordance with my invention these and various other important objects which will appear as the specification proceeds are accom lished by making use of substantiall roc ugly and rotatably disposed contamers, tanks, vats or the like, the

As heretofore practised, these various stages of treatment have usually much time and space were unduly consumed. With the 3 1s a diagram showing an elevation of a modified construction with one of the containers in the operative position.

The device may comprise a plurality of containers or vats f, g, but it should be understood that the invention is not limited to the use of but, two containers, inasmuch as for some purposes a greater number will be found necessary. The containers are rockingly or pivotally levers a which constitutea part of a frame or wheel pivoted at h and which may be goods without mounted at k, k onsame device with the containersin the inoperative position.

A crank handle p or equivalent means is adapted by means of a gear wheel 0 or the like engageable with a rack bar at on a frame member m upon which the wheel or rotatmotive power or the like.

able cross 1' mounted to act upon the same,

so as to raise and lower it with the containers, vats. buckets or the like suspended therefrom or pivotally secured thereto. a, d, e are guide rollers for the goods to be treated and which, in the exemplification shown, may be stationarily arranged with relatipn to the reciprocable and rotatable cross or wheel a, Z. The goods which are guided on these rollers are run off and taken 11 by the dyeing and treating rollers a, b.

en the carrier, wheel, support, cross or the like i, Z is in "the inoperative position of Fig, 2- in which the containers f, g are lowered, the goods to be treated may readily introduced into the machine, masmuch as the rollers, a, b, a, d, e are fully exposed and at a suitable distance from the containers, so that the goods will remain in the machine from beginning to end and may pass uninterruptedly to and fro onto and between the rollers a, b. This reciprocating air, to ,be oxidized and aired in the usual manner, when neither of the containers 1s in the operative position. By this means it becomes also possible to carry out a variety of working procedures in uninterrupted sequence and without the goods becoming substantially arrested in their passage from one roll to' the other and during the treatment. Thus, if the tank I is, for instance, moved into the operative position carrier 71 by means of the crank 12 and the gear wheel 0 or by an e uivalent device, the goods which are cause to pass from the roller a and by way of the guide rollers 0, d, 6 onto the roller b and inversely, may be preliminarily boiled or deprived of their size. While this working process is going on, the dyeing vat for the next dye: 11g operation may be prepared in the tank 9 which is now in the inoperative position. It frequently requires 20 minutes or more to develop such vats and this time is utilized-in the machine according to this invent-ion for the preparation of the goods. Then the tank 9 is moved into the operative position by lowering the carrier 11 and by turning the pivoted tanks f, g by means of the hand lever Z and by the subsequent raising of the carrier 2' so as to move the tank 9 into the operative position into engagement with the goods which are now given the desired shade. "During this time the-tank f which is now inoperative may be prepared for the next working procedure or step of rinsing or boiling and soaping the goods and so in succession.

It therefore appears that by means of this machine the important result is produced that the goods remain in the machine during the entire series of working procedures and are practically uninterruptedly moved and that the time required for any one o the steps or procedures may be utilized for the preparation of the next charge or procedure in the most favorable manner an that all these steps and procedures includ ing the airing may be carried out in one and the same machine and on the smallest pos- P sible space.

It is obvious that the invention is not restricted to any particular means of raising and lowering and laterally moving the various tanks, vats pr the like. In the modification shown diagrammatically in Fig. 3 the raising and lowering of the containers, tanks, vats or the like may be produced by a Windlass or similar means not shown in the drawing and operatively engageable with the containers 1;, on. These containers are, moreover, provided with laterally disposed supporting rollers u which are adapted to disa rail or by raising the be emptied and may d siderably greater an 1,eos,es2

placeably support the containers 1;, :1; u on ide a. In the drawing, the container 'v is shown raised' in the operative position, while the container x is lowered. In this position of rest the containers by means of the rollers w are supported on the guide or rail 2 and may be moved length- 1 wise thereof. When the container isin the proper position underneath the guide rollers t, s, u, it ma be vertically move by a windlass or the ike which preferably acts upon the bottom of the container. If it is, for instance, desired to move the container at to the operative position and the tank '0 to the inoperative position, the latter is lowered until it rests with its rollers upon the rail .2. It is then moved, for instance, towards the ,left in the direction ofthe arrow to the far end of the rail .2 and the container m is horizontally displaced upon the rail 2, until it is vertically below the guide rollers t, s, M. Then the raising means are operated to move the container as to the position previously occupied by the container '1). It will be advisable to dispose the raising and lowering device sideways with relation to the containers in a similar manner as in the case of freight elevators, so that the working parts of those raising means will not interfere with the free movement along the rail z. Thus, it will be seen that the several containers may be moved to the ino erative position by merely lowering and aterally moving the same along the rail 2. In the case of airing of the material, both containers f, 9 may be held at rest upon the rail 2.

With this modification, according to Fig. 3, there is the advantage that considerably larger containers or tanks and consequently a greater amount of liquor may be used than with the embodiment illustrated in Figs. 1 and 2 of the drawing. With this latter arrangement the dimensions of the containers should not exceed a certain limit, as otherwise the parts of the machine would become f too difficult to handle in practical operation,

while, with the modification shown in Fig. 3 it is possible to em 10y containers of conpractically unlimited dimensions, without any necessity of thereby increasing the dimensions of the other arts'of thedyeing or similar machine.

It should be understood that various other modifications may be made to suit the convenience of the operator and the particular conditions of the oods and other local requirements and wit out thereby deviating from the sec and spirit of the invention as 'particu pended claims.
